Abstract
Nanocomposite films based on biodegradable polylactic acid (PLA) and PLA/polyvinylpyrrolidone (PVP) with embedded stabilized Hydrozincite powder were synthesized by solution casting method. The Hydrozincite was prepared by plant extract-mediated hydrothermal synthesis. Powder X-ray diffraction analysis and Fourier-transform infrared spectroscopy were used to establish the phase composition and structure of the films. The photocatalytic activity of the obtained nanocomposite films was tested and compared in the reaction of degradation of Malachite Green dye under UV illumination. The photocatalytic results revealed that the PLA/PVP-containing Hydrozincite nanocomposite film leads to a higher degree of degradation of the Malachite Green dye (87 %) after 150 minutes in comparison to that of PLA/Hydrozincite (31%). The antibacterial activity of the prepared nanocomposite films against an Escherichia coli control strain was also discussed. The investigated biocomposite films demonstrated high antibacterial efficiency. It was found that the concentration of viable bacterial cells decreases by about 99% after 1 hour of contact time for both investigated composites.
